' AUTOMATIC FIRE-EXTINGUISHER.

a citizen otl the United States, and resident'.

et the city, county, and State of NewYork, have invented certain new and useful Improvements in Automatic Fire-Extinguishers, of which the following is a specification.

This invention relates to a device nl? at! tachment adapted to be used in connection with a tank, especially in connection With dyeing or cleaning apparatus in which the material iscieaned in a tank containing naphtha,

ignited and result in a disastrous and destructive tire which destroys the machinery and the goods contained therein.

rlfhe objeetof this invention is to provide a simple device which may be used in connection with these tanks and by means of which a fire extinguishing compound is automatically injected into the interior thereof when a fire occurs therein.

In carrying out the invention l provide a receptacle for the lire extinguishing compound which is mounted upon the tank in such a manner as not to interfere with its ordinary use. The receptacle is provided with means operative Whenever a re occurs inside the tank for automatically injecting the compound and for `vaporizing the' saine on the interioiof the tank in order to more effectively and rapidly extinguish the fire.

ln the drawingslike parts in the several views have been given the saine reference numerals.

Figure 1 is a sectional elevation ot a Washing or cleaning tank showing"- a device mounted thereon. Fig; 2 -is a sectional side elevation of the upper portion of sFig. 1. Fig. 3 is a rear view of Fig. 2. Fig. 4 is an enlarged sectional vieW of the upper portion of Fig. 1, showing the device in its operative position.

A Washing'or cleaning tank is shown at 1 and is provided with a hinged cover 2 attached to the same. A receptacle 3 for a fire extinguishing compound is mounted upon. the` cover 2 and is providedvwith a lower or outlet valve 'i and an upper valve or air 'vent 5. These valves are connected together and operated by the valvestem 6 and the lever 7, which is pivotally'molilnted at 8 upon the cover gasolene or similar fluids, which are very intl ammable and'frequently become p Specification of Letters Patent.

projecting upwardly through an opening in the cover 2 to the upper side thereof.

A lever 9 is pivotally mounted upon the pivot or hinge 10 of' the cover 2 and is normally held in its open position by means el? the spring 11, as shown in Fig. 4.-.

The lever 9 is provided with a latch i'. which when the lever is cls'sed projects l through an opemng in the cover 2 and engages beneath the holding member 13 which is 1n turn held by a fusible member 14 attached thereto and passing around a pin i5 and attached at its opposite end to the pin '16 on the other side of the cover 2.

A wick 17 is carried in al suitable holder 18 against the inner surface of the tank 1 and extends from the upper to the lower portion of the tank into the naphtha or other cleaning fluid.

Should a fire occur a portion ot the flame- Willl be concentrated at the upper end of the wick 17, which is positioned adjacent the fusible member 14, thus causing the same to be melted and releasing the member 13 which holds the latch 12. The latch 12 being beveled at the pointwvhere it engages the member 13 will be readily released and the lever '9 will fly back to the position shown in Fig. 4.

lVhen the lever 9 is in its closed position one end thereot1 engages the end of the lever 7 and holds the valves 4 and 5 in closed posi tion but when the same 'is released by the melting of the fusibleinember 14C, in the manner just described, the valves 4 and 5 Will drop to their open position ard'rel'ease the fire extinguishing compound/'from the receptacle 3, causing the same to be injected upon the' vaporizin plate 19,- Which is mounted upon the `un ey side of the cover 2. The vaporizing` plate 19 having become heated `by the `fire in the tank 1 causes the fire extinguishing corn ound injected thereupon to become\ rapi ly vaporized in the form of a fire extinguishing gas Which 1s distributed throughout the tank and is more effective and operates with greater rapidity 2 and formed with on@ end l to extinguish the fire.

It will thus be seen that a very simple attachment is provided which Wlll operate automatically when a fire occurs to inject and vaporize the fire extinguishing compound in the form of a non-combustion supporting gas which is extremely efiicient and effective and operates i'i'itligreat rapidity in "extinguiehing the iii-e.

It will be understood that the details of construction may be changed to adapt the device for use with various .forms of tanks, etc. A

lVhat I claim is:

1. A fire extinguisher Comprising a support, a receptacle for a iire extinguishing compound mounted thereupon,(means open ative automatically when a fire oecur for causing;` the fire extinguishing compound to ilow upon a vaporizer, and a Yaporizer coin- .prismgi` a plate attached to the support and providing' a space between it and the support and adapted to vaporize the-compound.

2. A fire extinguisher Comprising a support, a receptacle Afor compoundy mounted thereupon, means controlled by a fusible member adapted to opei`- ate automatically when a tire occurs adjacent said support for causing the fire extinguishing compound to ow from said receptacle7 and a wick fusible member.

3. A fire extinguisherI comprising a support, a receptaelefor a fire extinguishing Compound mount-ed thereupon, means Conpositioned adjacent said trolled by a. fusible member adapted to oper- J a fire extinguishing.

ate automatially when a fire occurs for causing the fire extinguishing'compound to How 4from said receptacle, a wick' Qn said support extending from the bottoni to the top adjacent said fusible member and means for supplying said wick with aA highly inlaimnable liquid. A

4. A re extinguisher comprising' a sup- "port,ra receptacle for a fire extinguishing Compound mounted on said support, valves at the upper and lower ends,l oi' said receptacle operativelyY connected together, a lever pivotally mounted upon said support oper-- and State of lNew York, thisfil'st day of' Jan., 1913.
